'EQIALL WHOM IT MAYl GONCERN:

Beit known that I, ANDREW ONEILL, of Portsmouth, in the county ofScioto, and State pf Ohio, havel invented a new and useful Improvementin Wash-Boilers; and I do hereby declare that the following isv asufciently full, clear, and exact description thereof, to enable oneskilled inthe art to which my said invention appertains, to make and useit, reference bei'ng had to the accompanying drawings, which are made apart of this specification.

'I'he subject of my invention is a removable inner boiler, of peculiarconstruction, adapted to be placed within a common boiler, and when soplaced,to induce an active and forcible circulationof watery-under theaction of heat. In thedrawings-f i Figurel is a central verticalsection, representing my wash-,boiler applied to a boiler made under myseveral patents of August 22,' 1865, and February 20, 1866.

Figure 2 is 'a .planof the same partly in section. Figure 3 represents aside elevation thereof, a portion of the outer boiler being removed toexpose that to whiclrmy present invention relatesf Y l Figure 4 is avertical section, showing the invention applied ito a commonagricultural kettle. Similar` letters of reference indicatecorresponding parts in the several views. i A represents an outerboiler, which may haof any common or suitable construction. B istheinner boiler, to which my invention relates. The said innerboiler' isseparate and removable from theouter boiler A, but, while in position-within the latter, is madeto it tightly by means'of an elastic orcompressible gasket, C, located at any proper height. -Below the gasketO is a range of apertures, D, passing through the wall of the innerboiler B, and extending completely around the same. On the inside, theapertures Diare vsurmounted by hoods E, presented radially toward thecentre; F F F represent a second range of apertures, located'near thebottom of 'the inner boiler. Deliectors G may be applied on the outside,under the apertures F, to prevent the hot water from beneath the innerboilerA entering through the saidapertures in its upward course. l

VIn some eases, I also propose to use directing-plates H, on the outsideof the inner boiler, to eonduct-th'e ascending water to'the apertures D.I represents a straining-cloth, placed above the clothes to arrest anyAinsoluble matter which may have been'once removed therefrom.

The operation is as follows l The. outer'boiler A is supplied withwater, and the clothesto be washed are placed in the inner boiler B.rIhe water in the bottom of the outer boiler, as it becomes het, willrise around the sides of the inner boiler, and being confined by thepacking-gasket, will be forcibly driven in through the apertures D, onto thetop of the clothes or on to the straining-cloth I above them. Hetwater is thus constantly applied to and forced through the clothes,'andpassing out through the lower apertures F, is as constantly-reheated inthe bottom of the outer boiler. I i i i An inner boiler, B, constructedas above described, and provided with a gasket, O, may be placed withina common cast-iron kettle er boiler of almost any form, andby keepingthe Aclothes from contact with the iron, Aprevents any danger ofiron-moulding. I thus, at a trilling oost, providel means whereby acommon boiler, which-is ordinarily used for other purposes, may beconverted at will into an automatic wash-boiler of the most ecientcharacter. l

The closure' effected by the gasket C, compels the ascending water toenter the boiler B through the apertutes D, and thus avoids thenecessity of a cover over the whole. When my inner boiler is applied toan outer boiler with straight sides, as illustratedin figs. 1, 2, and 3,the gasket will be received by a .swage. or rib, c, to support the innerboiler, with its bottom suliiciently above that of the outer boiler toleave the necessary water-space between them. v

-The upward convergence of the annular water-space between the twoboilers, imparts greater velocity to the water as it rises, and causesit to beejected'through the apertures D with great force.

By having no perforations in the bottom of the inner boiler, I preventthe reliux of ,steamand water upward through the bottom, which, inautomatic boilers heretofore constructed, causes great inconvenience bythrowing up the clothes, and interfering with the desired circulation ofwater.

I (lo not claim as new, so constructing a wash-boiler, that water willbe caused to circulate in it by the application of lient, as I am awarethat this is done in the Wash-boiler of M'. W. Staples, for whichLetters Patent were granted, February 12, 1867, and reissued,December17, 1867, angl in some others.

Having thus described m'y invention, I claim as new, and desire tosecure by Letters Patent- The removable inner boiler B, provided with apacking or gasket, C, and adapted for application to an outer boiler ofcommon construction, to constitute an automatic wash-boiler, asexplained.

ANDREW ONEILL.
